"Very happy with these filters. My own assumption is that pleated is better than the spun thread style. Most importantly though, these are Made in USA."
— Chris N. (5/5)
"Super easy to use"
— Eleanor L. (5/5)
"Very good filters"
— Alvin S. (5/5)
"I use this filter just up-stream of a US Water Systems carbon block filter on my houseboat on Lake Powell. These pleated filters have never failed us and that is so critical when the folks on our boat depend on having clean and safe drinking water. I just can't justify saving a few bucks on a foreign made filter where the health of my friends and family is concerned."

"Found filters that are made in our own country, that is awesome, Too bad that they cost 2-3 times more than comparable others. We really would like to change them more often."
— Linda L. (4/5)
"Can’t review when I never received what I ordered. It’s been 22 days and multiple calls to company and still nothing. So much for a first time customer wanting to try American made products and support American company. Honestly disappointed. The other products I ordered also not performing to my prior products capability."

"Does a great job."
— Leroy W. (5/5)
